For the first time, Google has invited the world to explore its secretive data centers.
The Internet giant Wednesday took several steps to show users how its data centers work, including putting out a YouTube video, which you can see above.
Among the video's highlights, at the 1:15 mark you can see how Google destroys its hard drives after they break so no one can steal the data.
Recently, Google and others in the tech sphere have come under criticism for their energy-hogging data centers. To give people an idea of what exactly those centers do and what steps the company is taking to use energy efficiently, Google gave Wired's Steven Levy and CBS a firsthand look. You can see the CBS report below, which includes an interview with Urs Hölzle, Google's "infrastructure czar" and senior vice president.
